Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an infusion set for surgical care. Background Art

[0002] Surgical care is a highly specialized nursing discipline, mainly targeting the whole process of care for surgical patients before, during, and after surgery, and there is no shortage of infusion operations on patients.

[0003] An infusion set, also known as an intravenous infusion device, is a medical device used to infuse liquid medicine into a patient's body through a vein. The entire infusion set mainly consists of an infusion bottle or infusion bag, an infusion tube, a regulator, a drip chamber, a filter, a needle, etc. The use of an infusion set requires strict aseptic operating procedures to prevent infection. Medical staff will set the infusion rate according to the doctor's order and the patient's specific situation, and regularly check the infusion set and the puncture site to ensure the safety and effectiveness of the infusion.

[0004] However, during the clinical infusion process, generally, the patient's family member or the patient performs the operation of opening the clamp. It has been found clinically that some family members cannot operate or will break the clamp during the operation, or some family members are afraid of operating the clamp and can only directly ring the bell to call the nurse. In this way, it will inevitably increase the workload of the nurse. Medical staff will promptly remove the needle and guide the patient or family member to correctly press the puncture site to prevent bleeding or congestion. However, when the number of infusion patients is large and the number of relevant medical staff is insufficient, medical staff often cannot take care of each patient in a timely manner, resulting in some patients not being able to remove the needle in time after the infusion is completed, and then when the pressure in the blood vessel is higher than the pressure in the infusion set, the phenomenon of blood flowing back into the infusion tube occurs. The blood return in the infusion set will cause local blood vessel dilation, resulting in slight pain, and cause poor local blood circulation, resulting in blood stasis and swelling, and may even lead to a certain risk of thrombosis. For this reason, we propose an infusion set for surgical care. Summary of the Invention

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-7, the present invention provides a technical solution: an infusion set for surgical care, including a first shunt tube 1 and a second shunt tube 2. A connecting sleeve 4 is detachably connected between the first shunt tube 1 and the second shunt tube 2. A transition chamber 5 is fixedly connected to the bottom between the first shunt tube 1 and the second shunt tube 2. Upper connecting pipes 9 are fixedly connected to the bottoms of both the first shunt tube 1 and the second shunt tube 2. A collecting pipe 7 is fixedly connected between the bottoms of the two upper connecting pipes 9. A connecting cavity 6 is fixedly connected between the collecting pipe 7 and the transition chamber 5. A lower connecting pipe 8 is fixedly connected to the bottom of one end of the collecting pipe 7. The first shunt tube 1, the collecting pipe 7, and the lower connecting pipe 8 are interconnected. A connecting rope 15 is movably connected between the first shunt tube 1 and the lower connecting pipe 8. A floating ball 14 is fixedly installed at the top of the connecting rope 15. A counterweight ball 29 is fixedly connected to the bottom of the connecting rope 15. The lifting plate 19 is fixedly connected to the connecting rope 15; the materials of both the first shunt tube 1 and the second shunt tube 2 are made of transparent silicone material, and the pipes of the exhaust valves are connected to the tops of both the first shunt tube 1 and the second shunt tube 2; the tops of the first shunt tube 1 and the second shunt tube 2 are respectively connected to the infusion bottles, which allows the infusion bottles to be directly put into use without changing the medicine. The connecting sleeve 4 helps the first shunt tube 1 and the second shunt tube 2 to be stable when placed in a certain area. When in use, the infusion bottles are respectively connected to the first shunt tube 1 and the second shunt tube 2. After the medicine enters the first shunt tube 1 and the second shunt tube 2, first, after the floating ball 14 generates buoyancy, it floats inside the first shunt tube 1, causing the floating ball 14 to pull the connecting rope 15 and the counterweight ball 29 to rise. Among them, the counterweight ball 29 has a certain limit on the rising height of the floating ball 14 to prevent the floating ball 14 from rising too far and blocking the inlet at the top of the first shunt tube 1;

[0028] Specifically, a connecting plate 22 is fixedly installed at the bottom of the transition bin 5, and a plurality of connecting handles 20 are fixedly installed at the inner bottom of the first shunt pipe 1. A guide rail 21 is slidably connected to each connecting handle 20, and a lifting plate 19 is fixedly installed between the plurality of guide rails 21. One end of the transition bin 5 is movably connected to an elastic sheet 25 at the end facing the first shunt pipe 1. One end of the elastic sheet 25 is fixedly connected to a connecting membrane 2501. A water filtering block 33 is fixedly installed at one end inside the manifold pipe 7. The connecting membrane 2501 penetrates the connecting cavity 6 and extends into the water filtering block 33. A fixing block 31 is fixedly installed at the inner bottom of the manifold pipe 7. A second spring 32 is fixedly connected between the fixing block 31 and the connecting membrane 2501. Water passing holes 34 are formed in the connecting membrane 2501; a fixing strip 24 is fixedly installed at the top of the connection between the transition bin 5 and the first shunt pipe 1. One end of the elastic sheet 25 is fixedly connected to the transition bin 5 through the fixing strip 24. A limiting strip 26 is fixedly installed at the top of one end of the connecting plate 22. A limiting mound 28 is fixedly installed on one side of the elastic sheet 25. A plurality of damping mounds 27 are fixedly installed at equal intervals on the top of the connecting plate 22 near the limiting strip 26; when the inside of the first shunt pipe 1 is not filled with liquid, the initial position of the lifting plate 19 is at the bottom of the first shunt pipe 1, and is restricted and interfered by the arched part of the elastic sheet 25. When the first shunt pipe 1 and the second shunt pipe 2 are filled with liquid, the floating ball 14 receives an upward buoyancy force, so that the connecting rope 15 drives the lifting plate 19 to rise together. Then, the lifting plate 19 rises along the guide rail 21 through the connecting handle 20. The edge of the lifting plate 19 interferes with the arched part of the elastic sheet 25, so that the lifting plate 19 drives the elastic sheet 25 to deform, causing one end of the elastic sheet 25 to move away from the first shunt pipe 1, and the limiting mound 28 on the elastic sheet 25 slides on the damping mounds 27 until the limiting mound 28 stops between two adjacent damping mounds 27. The lifting plate 19 breaks through the restriction of the elastic sheet 25, so that the second spring 32 changes from the stretched state to the original normal state, so that one end of the connecting membrane 2501 moves towards one end inside the manifold pipe 7 following the second spring 32, making the water passing holes 34 on the connecting membrane 2501 located below the water filtering block 33, away from the channel of the water filtering block 33, and making the side surfaces of the water filtering block 33 and the connecting membrane 2501 contact each other, preventing the infusion bottle on the first shunt pipe 1 from being used while the infusion bottle on the second shunt pipe 2 is in use;

[0029] Immediately afterwards, a push rod 3 is movably connected to the bottom of the second shunt pipe 2. A first sealing ring 301 is fixedly installed on the push rod 3. The connection between the transition bin 5 and the second shunt pipe 2 is in a closed state. One end of the push rod 3 is movably connected to the transition bin 5. One end of the push rod 3 is fixedly connected to a movable block 23. When the floating ball 14 rises, the medical staff or family member holds the push rod 3 by hand, holds one end of the push rod 3 and pushes it into the second shunt pipe 2, so that the other end movable block 23 of the push rod 3 slowly contacts the inner side of the elastic sheet 25 and pushes the elastic sheet 25 to the position as shown in the attachmentFigure 4 and attached Figure 6 The position of the limit hill 28 and the limit strip 26 can be offset, the second spring 32 is in a stretched state, the water hole 34 and the water filter block 33 are staggered, and then the push rod 3 is manually controlled to work, so that the position of the movable block 23 is maintained above the middle of the multiple damping hills 27, which helps to communicate the water hole 34 with the channel of the water filter block 33 after the elastic sheet 25 moves again and its inner side contacts the movable block 23, so that the liquid medicine flows out from the water hole 34;

[0030] When the float 14 rises, if the liquid in the hanging bottle connected to the first shunt tube 1 is used up, the liquid level in the first shunt tube 1 gradually becomes lower. After the float 14 falls, the weight ball 29 falls, so that the connecting rope 15 drives the lifting plate 19 to fall. The weight ball 29 has a certain dead weight, so that the edge of the lifting plate 19 contacts the arched part of the elastic sheet 25 again, so that the limit hill 28 and the damping hill 27 on the elastic sheet 25 are separated, and the inner side thereof contacts the movable block 23. The water hole 34 and the channel of the water filter block 33 are connected, so that the medicine inside the second diversion tube 2 is replenished to the other end of the collecting tube 7 through the water hole 34 and the water filter block 33, and then flows to the lower connecting pipe 8, which reduces the workload of medical staff to frequently replace the hanging bottles and improves the use time of the medicine. After the medicine inside the second diversion tube 2 is used up, it is reset by manually holding the push rod 3, and the hanging bottles above the second diversion tube 2 and the first diversion tube 1 can be replaced together.

[0031] Furthermore, a partition 35 is fixedly connected to the middle of the manifold 7, and a one-way valve 36 is fixedly installed on the partition 35. The output direction of the one-way valve 36 is away from the connecting membrane 2501. The outer diameter and inner diameter of the water hole 34 and the one-way valve 36 match each other. The one-way valve 36 can prevent the liquid medicines at both ends of the manifold 7 from mixing, which helps to use various liquid medicines in sequence, so that the efficacy of the medicines can play a great role in the human body.

[0032] Furthermore, a filter plate 18 is fixedly installed on the middle part of the inner wall of the first diversion pipe 1, and a plurality of first springs 17 are fixedly connected upward at the top edge of the filter plate 18, and a cover plate 13 is fixedly connected to the common top of the plurality of first springs 17, and the edge of the cover plate 13 abuts against the first diversion pipe 1, and the diameter of the float 14 is larger than the inner circle diameter of the cover plate 13. When the medicine inside the first diversion pipe 1 is used up, the counterweight ball 29 pulls the connecting rope 15 to descend, thereby pulling the counterweight ball 29 downward and the float 14 descends, wherein the float 14 contacts the center of the cover plate 13 during the descent, so that the cover plate 13 is blocked and the cover plate 13 is descended, thereby preventing the medicine in the second diversion pipe 2 from flowing into the first diversion pipe 1 through the collecting pipe 7.

[0033] Furthermore, a pipe joint 12 is fixedly connected to the bottom of the lower connecting pipe 8, and a drain cover 30 is fixedly installed on the top of the lower connecting pipe 8. The drain cover 30 is in the shape of a funnel, and the bottom diameter of the drain cover 30 is smaller than the diameter of the counterweight ball 29. When there is liquid medicine inside the first diversion pipe 1, the float 14 generates buoyancy, and the drain cover 30 can effectively prevent the outside of the counterweight ball 29 from contacting the top of the lower connecting pipe 8, thereby effectively preventing the occurrence of poor water flow from the top of the lower connecting pipe 8.

[0034] Furthermore, the interior of the collecting pipe 7 is divided into a medicine liquid mixing area and a liquid to be replenished area by a partition 35. The liquid to be replenished area is communicated with the second shunt pipe 2, and the medicine liquid mixing area is communicated with the bottom of the first shunt pipe 1. A filter cover 37 is installed in the medicine liquid mixing area. The inner circle of the filter cover 37 is slidably connected to a sponge block 38. A connecting rod 39 is fixedly connected to one side of the sponge block 38. A second sealing ring 40 is sleeved on one end of the connecting rod 39. A screw 11 is fixedly connected to one end of the connecting rod 39. A rotating block 10 is rotatably connected to one end of the collecting pipe 7. The rotating block 10 and the screw 11 are threaded together. When the first shunt pipe 1 or the second shunt pipe 2 is filled with particles, the insoluble particles in the medicine will inevitably enter the human body through intravenous infusion or intravenous injection. Since it is difficult to be cleared by the immune system, it will remain in the human body for a long time and accumulate in specific parts. The insoluble particles are stacked and accumulated in the filter cover 37, which will eventually cause serious harm to the human body. Therefore, after the medicinal liquid passes through the filter cover 37, the insoluble particles are first adsorbed by the filter cover 37. When the device is not in use, the rotating block 10 can be manually rotated so that after the rotating block 10 is rotated, the screw rod 11 drives the connecting rod 39 and the sponge block 38 to move inside the filter cover 37 to remove the insoluble particles in the filter cover 37. Then, the rotating block 10 is manually rotated in the opposite direction, and the screw rod 11 is moved in the opposite direction to take the sponge block 38 out of the filter cover 37, and then a new sterilized medical sponge is replaced. At the same time, the sponge block 38 and the filter cover 37 can also absorb the blood that penetrates the human body to prevent a large amount of blood from flowing back and causing discomfort to the human body, and to prevent blood from accumulating outside the human body.

[0035] Furthermore, a piston 16 is fixedly connected to the connecting rope 15, and the piston 16 is movable between the collecting pipe 7 and the first diversion pipe 1. The outer and inner circles of the piston 16 and the upper connecting pipe 9 have the same diameter. When the float 14 descends, the piston 16 generates downward pressure on one of the upper connecting pipes 9, forming a sealed state for the top of the upper connecting pipe 9. When the piston 16 has no liquid medicine inside the first diversion pipe 1, the counterweight ball 29 has a certain pulling force on the connecting rope 15, which can effectively prevent the liquid medicine inside the second diversion pipe 2 from flowing back into the first diversion pipe 1 through the upper connecting pipe 9, thereby mixing the liquid medicine inside the first diversion pipe 1, saving the operation steps of the first diversion pipe 1.
